Tough Empathy (Romans 12:15, 16)

We have a human tendency where we would rather rejoice when we see people suffer and weep when we see people get ahead of us. We might say that this is not our struggle, but then why does Paul exhort us to weep with those who weep and rejoice with those who rejoice? The reason is because this is not natural, but something we do in the Spirit. How does this type of empathy become part of of who we are? How does this mindset cultivate a Christ like humility?
